Tesla’s stock story just got a fresh twist: Piper Sandler’s new DCF work values the company’s 17 modeled product lines at roughly $400 per share and explicitly leaves Tesla’s upcoming Optimus humanoid robot out of that base case, effectively suggesting that buying near current prices includes Optimus as optional upside at no extra cost.
Piper Sandler analyst Alexander Potter lays out an updated “Definitive Guide to Investing in Tesla.” He breaks the business into 17 distinct product lines, from vehicles to energy storage, Supercharging, insurance, FSD subscriptions, and the robotaxi concept, then runs a 20-year discounted cash flow on each slice. The result is a combined valuation that lands around $400 per share, which the note describes as “just shy of TSLA’s current share price.”
Potter singles out what he left out on purpose. “Critically, this analysis excludes Optimus, Tesla’s forthcoming humanoid robot,” Potter wrote. “In other words, at $400/share, we think investors can buy Optimus for ‘free’.” That framing is dramatic, but it’s meant to highlight the optionality rather than dismiss the robot’s potential value.
He is cautious about pinning a firm number on a product that could change labor markets and productivity in ways that are hard to forecast. Potter calls Optimus and a related “inference-as-a-service” business “thesis-defining products that, arguably, will be worth more than Tesla’s other businesses combined,” he said. The point is that assigning precise cash flows today would be speculative, not reckless, and the note treats Optimus as upside rather than baked-in value.
There’s also math behind the headline. Piper Sandler holds a $500 price target on the stock, unchanged, and that simple arithmetic implies $100 per share of unmodeled upside. That leftover $100 is the buffer for Optimus, inference-as-a-service, and any other nascent ventures that don’t fit cleanly into traditional auto valuation buckets. Potter admits even that $100 is conservative, writing, “Some would argue that’s far too low (we’re inclined to agree).”
Critics will point to the multiple being used in the model — a lofty 233x FY27 earnings multiple, up from 180x — which makes the base-case valuation richer and the “free Optimus” line a bit more conditional. Potter argues this premium is sensible because many sell-side models miss or underweight Tesla’s less obvious revenue streams. “We think most sell-side modeling efforts ignore the financial impact of in-house insurance, Supercharging, and other outside-the-box revenue streams,” he wrote.
Potter also flags where prior work fell short. He notes a prior model “lacked a serious attempt to reflect the 2025 CEO compensation plan, and it didn’t assign a specific value to the robo-taxi business.” Those omissions can materially change the picture, and the updated guide tries to fold them in while still reserving room for game-changing innovations that are difficult to forecast.
On near-term numbers, Piper’s revenue and EPS projections for 2026 and 2027 sit below consensus, reflecting slower deliveries, discontinued models, and reduced regulatory credit contributions. But Potter downplays the damage an earnings miss might do to the long-term multiple, writing, “If we’re right, and if TSLA misses consensus, we don’t think the resulting valuation headwinds, if any, will last long.” The thesis is that investors are increasingly buying the optionality on autonomy and AI, not just cars sold this quarter.
Tesla’s disclosures, like revealing 1.1 million active FSD subscribers in Q4 2025, feed this narrative that traditional auto metrics are losing relevance. “Historically relevant metrics are growing less important. As long as robotaxi- and FSD-related metrics keep improving, we think there’s support for at least $400/share.” That shift in investor focus underpins Piper’s tolerance for a high multiple today and bolsters the idea that Optimus is upside you get when buying near current prices.
